Basic automatic headlights work through sensors that detect how much light is outside the vehicle. Most times, these sensors are located on the dash of the vehicle. The headlights turn on when the sensors detect a certain level of darkness.
A:A bad speed sensor most often affects the shifting of the automatic transmission. However, in cars with an onboard computer, the sensor also affects the ABS system, speedometer, cruise control and power steering. Proper diagnosis and repair is essential for safe operation of the car.
A:Some of the most common causes for a car's stalling whilst driving include: a poor idle speed control, or ISC, system, low fuel pressure, loss of ignition and vacuum or EGR leaks. Diagnosing the specific problem should be a priority in order to get it fixed.
A:A passive restraint system does not require anyone to do anything manually to make it work. An airbag is an example of a passive restraint system. When a vehicle’s sensors detect an impact, the airbag automatically deploys. Seat belts, unless automated, do not fall under the true definition of “passive” as a manual action secures the belt to its clasp.
A:According to Future Cars, advantages of hydrogen fuel cells include non-corrosion, water vapor emissions and an indefinite fuel source. One disadvantage is the excessive carbon dioxide emissions when making hydrogen fuel cells; another is the fact that replacing fossil fuel infrastructure with fuel cells requires a massive investment in the billions or trillions of dollars.
A:Although laymen often use the words "motor" and "engine" interchangeably, from a technical point of view, an engine uses fuel to create heat that it converts into motion, while a motor uses electricity to produce motion. Historically, an engine is technically any machine that converts energy into force, such as a catapult, according to Reference.com.
A:Though its exact position on each vehicle may vary, the fuel filter is generally located between the fuel pump and fuel tank. Its function is to remove impurities from gasoline being pulled into engine, keeping the fuel injectors clean.
A:The short answer is yes, with the air conditioning running the car burns more gas than without it. When the compressor runs, more engine power is in use, and therefore more gas is burned in the process.
A:If a driver is parking a car facing downhill, he should turn the wheels so that they face the right side and engage the parking brake. It should be noted that this is for use in the U.S., or wherever drivers use the right side of the road.
A:The airbag light comes on when the backup battery is drained or damage has occurred to the clock spring or the airbag module. Because the light can have many causes, a technician must diagnose the problem if the light stays on.
A:Symptoms of a bad ignition switch include failure of the engine to turn over when the key is turned to the "start" position and failure of the radio or headlights to work when the key is in the "on" position. They also include a car that stalls out frequently when idling and an ignition switch that is very hot to the touch.
A:Use clear packing tape as a temporary fix, as this provides a great seal that you can see through. Be sure as much dirt and dust is removed as possible from around the window where the tape is to be applied.
A:A smell of sulfur coming from a car's exhaust pipe is a good sign that there is a problem with the catalytic converter, according to Cars Direct. The smell, similar to rotten eggs, indicates that the sulfur present in gasoline is not being converted to odorless sulfur dioxide.
A:According to Progressive, the best types of hail protector for a car are personal covered parking ports, temporary shelter such as mall parking garages, and car covers or blankets. Temporary shelters, such as mall parking garages, are useful for waiting out storms to avoid vehicular damage.
A:Basic automatic headlights work through sensors that detect how much light is outside the vehicle. Most times, these sensors are located on the dash of the vehicle. The headlights turn on when the sensors detect a certain level of darkness.
A:The first step in fixing a deep scratch on a car is to apply a polishing compound. This will remove the clear coat on the exterior of the car. Next, it is important to ensure the paint color used will seamlessly match the automobile.
A:If the battery light comes on while driving, it means the alternator is not producing electricity and thus the car is running only on battery power. The safest thing to do when this light comes on is to pull over safely and try to locate the problem.
